14. Solve 10 + 6(-9 – 4x) = 10(x - 12) + 8.
O A. X = 17
OB. X = 2
O C. X = -18
O D. X = -6​

Answer: A

Step-by-step explanation:

[tex]a^{2} + b^{2} = c^{2}[/tex]

A and B are the legs of the triangle, and c is the hypotenuse. A would make the most sense.

The sum of the squares of the lengths of the legs of a right triangle equals the square of the length of the hypotenuse.

" In a right angled triangle the square of the hypotenuse is equals to the sum of the square of the other two sides of the right angled triangle."

According to the question,

As per the Pythagoras theorem ,

(Hypotenuse)² = (Adjacent side)² + ( opposite side)²

Hence, we conclude that Option A is correct.

Answer:

Length is 12 and width is (x+4) means 16

Step-by-step explanation:

Given:

Area of cookie sheet = 192 in²

Area = x² + 4x

Computation:

x² + 4x = 192

x(x + 4) = 192  , The length is x and width is (x+4)

x² + 4x -192 = 0

x² + (16 + 12)x -192 = 0

x² + 16x + 12x -192 = 0

x(x + 16) - 12(x + 16)

(x + 16)(x - 12)

Because length can not be negative (-16) so,

Length is 12 and width is (x+4) means 16

Answer:

25%

Step-by-step explanation:

The formula that we can use in this problem would be:

$decreased / Original $

So we would have

28-21 / 28

7 / 28

1/4

1/4=25

So, the percent decrease if 25%

Answer:

25

Step-by-step explanation:

Formula for percent increase or decrease:

(new number - old number)/(old number) * 100%

In this case,

old number = $28

new number = $21

Plug numbers into formula:

($21 - $28)/($28) * 100%

= -$7/$28 * 100%

= -0.25 * 100%

= -25%

A negative answer means a percent decrease.

A positive answer means a percent increase.

The percent change here is -25%, so it is a percent decrease of 25%

Answer:

The number of path we can take to walk from A to B via a 7 unit path while staying on the grid is 35 paths

Step-by-step explanation:

Given that we are to walk via a 7 unit path, we have;

Path to walk = Right or Left from start point A

Total number of rights and left to get to point B from A must be= 7

Left direction=3 turns

Right direction=4 turns

Number of ways for the first turn = 7, the next turn has 6 ways after that 5, then 4 next, 3 next, 2 next and 1

7 × 6 × 5 × 4 × 3 × 2 × 1 out of which

four are in the right direction in 4 × 3 × 2 × 1 ways and

3 are in the left direction in 3 × 2 × 1 ways,

Number of ways=7! / 4!3!

=7*6*5*4*3*2*1 / 4*3*2*1*3*2*1

x + y + z = 40

2x + 3y + 3z = 110

x + y + 2z = 50

When you dive 9 by 3 you get 3.

When you divide 7.3 by 2.2 you get 3.318181818...

Rewrite the product as

[tex]13^4\cdot 17^2\cdot29^3 = (10+3)^4 (10+7)^2 (20+9)^3[/tex]

Powers of 10 and multiples of 10 don't contribute to the units digits, so we only need to consider the product

[tex]3^4\cdot7^2\cdot9^3=81\cdot49\cdot729[/tex]

and we can treat this the same way:

[tex]81\cdot49\cdot729=(80+1)(40+9)(720+9)[/tex]

Again, ignore the multiples of 10 to reduce this to the product 1*9*9 = 81, whose units digit is 1.

P(X and Y) =0.2, P(X or Y)=0.7

Step-by-step explanation:

P(X or Y)

P(X∪Y) = P(X)+P(Y) - P(X∩Y)

=  0.5 + 0.4 - 0.2

=  0.7

or 1-P(Y|X)=1-0.3=0.7

P(X and Y)

P(X∩Y) = P(X) × P(Y)

=  0.5 × 0.4

=  0.2

Answer:

1) 244.92cm  2) 188.68 km  3) 3m

Step-by-step explanation:

1) We are finding the circumference of the basketball in this situation. C=pi(d), d=diameter, C=circumference. So, C= 3.14(78), and finally C= 244.92 cm.

2) We can begin to approach this problem by finding how far each car has traveled over 2 hours. The car heading north is going 50 km/h, so for two hours it has covered 100 kilometers. The car going west is at 80 km/h, so for two hours it has covered 160 kilometers. Now, we could draw this as a right triangle, with one leg being the north-headed car 100 km away from the start, and the other leg being the west moving car 160 km away from the start. The hypotenuse represents the distance between them. Now we use the pythagorean theorem! north car is a, west car is b. a^2+b^2=c^2. 100^2+160^2=c^2. 35600=c^2. take the square root of both sides for c=188.68. The distance between the two cars is approx 188.68 km.

3) `This situation can be represented as a right triangle. The height of the tree, 4m, is the height of the triangle, and the wire, 5m, is the hypotenuse. We are trying to find one of the legs, which represents the ground to the base of the tree. In the pythagorean theorem, we have a^2 and c^2, and just need to find b^2. Let's plug it into the equation:

4^2+b^2=5^2

16+b^2= 25

b^2=9

b=3

Answer:

B, they are the same line.

Step-by-step explanation:

Begin by converting each equation to slope-intercept form to make it easier to see the relationship:

-3x - 4y = 1

-4y = 3x + 1

y = -3/4x - 1/4

-------------------

-6x - 8y = 2

-8y = 6x + 2

y = -3/4x - 1/4

The lines are the same. Therefore, B is the correct choice.

Answer:

Step-by-step explanation:

Basic proportionality question. All we need to here is to expression the given fractions ( [tex]11 \frac{2}{3}[/tex], and [tex]1 \frac{17}{18}[/tex] ) as a fraction itself, and hence expressing the ratio we need to get, in fraction form.

[tex]11 \frac{2}{3} / 1 \frac{17}{18}\\\\[/tex] - So, we have expressed this in a fraction, which we want to reduce

[tex]= \frac{35}{3} / \frac{35}{18}[/tex] - The fractions have been taken as improper fractions

[tex]\\\\= \frac{35}{3}( \frac{18}{35} )\\ \\[/tex] - Now we took the inverse fraction, through multiplication

[tex]= 18 / 3[/tex] - 35 and 35 cancel out, leaving us with the simplified fraction 18 / 3

_____

So now we have 18 / 3, the ratio in fraction form. The scale is thus 18 to 3, or in other words 18 : 3.

Answer: 200 in

Step-by-step explanation:

Try to split up the face into pieces. You can make the first piece the square on the top. Only, you don't know the value of the bottom side, but you can see that it is 10 (if you look at the top at the back). So, if you do your multiplication, 10 x 10 = 100. So, that is the area of the first square. The next square also has a width and height of 10, (10 on the bottom, and follow the side to the other 10). Do the multiplication again (same as above) and get 100. Now that you have the area of the two pieces, you add then together: 100+100=200

Please feel free to let me know if you have any questions!

Answer: The yellow face has an area of 200 in^2

Answer:

The value of x in this equation is 12.

Step-by-step explanation:

4x - 20 = 2x + 4

Subtract 2x from 4x because they are like terms. Both terms have a variable of x attached to them.

2x - 20 = 4

Add 20 to 4 because they are also like terms.

2x = 24

Divide 2 on both sides of the equation so we can get x by itself and see what x is equals to.

x = 12

So, the value of x in this equation is 12.

Answer:

x = 12

Step-by-step explanation:

4x - 20 = 2x + 4

4x - 2x = 4 + 20

2x = 24

x = 24/2

x = 12

Answer: The number of different ways (orders) she can add these fruits to her blender = 24

Step-by-step explanation:

Given, Ella makes a smoothie for breakfast every morning. Today, she wants to use melon, apple, orange, and peach.

i.e. Total fruits = 4

The number of ways to order n things = n!

Therefore, the number of different ways (orders) she can add these fruits to her blender = 4!

= 4 x 3 x 2 x 1

= 24

Hence, the number of different ways (orders) she can add these fruits to her blender = 24

Answer:

a shaded region below a dashed boundary line

Step-by-step explanation:

this inequality uses the "less than" symbol (<), so we will use a dashed line because we are not including the values on the line

plug in (0,0) to see if we are shading above or below the line

0 < -1/2(0) + 5

0 < 5

this is true, so we will shade in the side that the point (0,0) is located, which is below the line (we know this because the inequality has a y intercept of 5)

The statement "Solving absolute value inequalities requires solving compound inequalities" is False.

Absolute value inequalities and compound inequalities are two different types of inequalities, and solving them involves different methods. Here's a brief explanation:

Absolute value inequalities: An absolute value inequality involves an expression enclosed within absolute value symbols [tex](| |)[/tex].

To solve such an inequality, follow these steps:

Compound inequalities: A compound inequality consists of two or more inequalities joined by the logical operators "and" or "or."

x ≥ $17, 500

Step-by-step explanation:

To find the cost of the next year model, we will follow the steps below;

Let x be the value of next year's model

$14000 ≤ 80% of  x

80% of  x ≥  $14000

80% × x ≥$14000

80x/100    ≥  $14000

multiply both-side of the equation by 100

80x ≥  $1400000

Divide both-side of the inequality by 80

80x /80 ≥ $1400000 / 80

x ≥ $17, 500

Therefore the cost of next year's model is

x≥$17, 500
